My father is 78 years old and was admitted into the hospital for hallucinations. They have given him meds to help him sleep, but it’s not working. When he gets sleep, he seems to be more himself, but for some reason he can’t sleep and he is so tired. What do we do? He’s talking out of his head, sometimes he doesn’t know who we are. The hospital done several tests including UTI and for infection. He has a bad heart. Please help!
